DETAILED DESCRIPTION

The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses.

With initial reference to FIG. 1, a suture device according to the present teachings is illustrated at reference numeral 10. The device 10 includes a main body 12 and an extended or elongated shaft portion 14 that extends from the main body 12.

The main body 12 includes at least one button, switch, or any other device suitable for operating the device 10. As illustrated, the main body 12 includes a first button 16, a second button 18, and a third button 20. The device 10 can include any suitable number of buttons for operating or activating the device 10.

The extended shaft portion 14 includes a proximal end 22 and a distal end 24. The proximal end 22 is mounted to the main body 12. The distal end 24 is opposite to the proximal end 22.

With additional reference to FIG. 1A, the distal end 24 includes a pointed conical tip 26, a first retractable wing 28, a second retractable wing 30, a first needle 32, and a second needle 34.

The pointed conical tip 26 is designed to pierce tissue, such as soft tissue, muscle, and bone. The pointed conical tip 26 can be sharpened to facilitate piercing the tissue. The pointed conical tip 26 includes or defines a pair of openings 36 connected by a slot 37. The openings 36 can be located at any suitable location on the tip 26. The slot 37 extends between the openings 36 across a distal portion of the tip 26.

The first and the second retractable wings 28 and 30 are positioned at opposite sides of the distal end 24. The first and the second wings 28 and 30 can take the form of any device suitable for supporting a suture. As further illustrated in FIG. 2A, each of the first wing 28 and the second wing 30 include a suture guide 40 and a needle opening 42. The suture guides 40 can take the form of any suitable device for guiding a suture from the extended shaft portion 14 around the wings 28 and 30 and to the tip 26. For example, the suture guides 40 can take the form of recesses, indentations, or c-channels formed in the wings 28 and 30. The needle openings 42 are openings in each of the first wing 28 and the second wing 30 that extend completely through each of the first and second wings 28 and 30 and are each sized to receive one of the needles 32 and 34.

Each wing 28 and 30 is movable between a retracted position (FIG. 1A) in which the wings 28 and 30 do not extend from the distal end 24 and an extended position (FIG. 2A) in which the wings 28 and 30 do extend from the distal end 24. The wings 28 and 30 are movable to the extended position by actuating the first button 16 (FIG. 2) and are movable to the retracted position by actuating the third button 20 (FIG. 4), as further described herein.

With additional reference to FIG. 3A, the first and second needles 32 and 34 can be any suitable device capable of penetrating biological matter, such as meniscal tissue, and capturing and/or retaining a suture. The first and second needles 32 and 34 can each include a retention surface or notch 44 and 46 respectively. The retention surfaces 44 and 46 can be any suitable surface or device for retaining and/or capturing a suture. For example, the retention surfaces 44 and 46 can be hooks or notches formed within each of the first needle 32 and the second needle 34 respectively.

The first and second needles 32 and 34 are positioned at opposite sides of the distal end 24. A position of the first needle 32 corresponds to a position of the first wing 28. A position of the second needle 34 corresponds to a position of the second wing 30.

The first and the second needles 32 and 34 are movable between a retracted position (FIGS. 1A and 2A) and an extended position (FIG. 3A). In the retracted position, the first and second needles 32 and 34 do not protrude from the extended shaft portion 14. In the extended position, the first needle 32 extends through the needle opening 42 of the first wing 28 and the second needle 34 extends through the needle opening 42 of the second wing 30. The first and second needles 32 and 34 are prealigned with the needle openings 42 so that when the needles 32 and 34 are moved to the extended position the needles 32 and 34 extend through the openings 42. The first and second needles 32 and 34 can be moved from the retracted position to the extended position by pressing the second button 18 (FIG. 3). The needles 32 and 34 return to the retracted position after reaching the extended position, as illustrated in FIG. 4A. The needles 32 and 34 are returned to the retracted position using any suitable device, such as a spring mechanism.

The distal end 24 is configured to receive any suitable fastening device for use in repairing a menicsal tear. The fastening device is illustrated as a suture 48. When in use, the suture 48 is mounted to the distal end 24 such that a first end 50 of the suture 48 is mounted to, or proximate to, the first wing 28 and a second end 52 is mounted to, or proximate to, the second wing 30. From the first end 50, the suture 48 extends along the first wing 28 within the suture guide 40 to the tip 26, where the suture 48 passes through the opening 36 and into the distal end 24. The suture 48 extends within the distal end 24 and then returns back to the tip 26 at a loop 54. The suture 48 extends back through the opening 36 to the second wing 30. The suture 48 extends around the second wing 30 to the distal end 24 along the suture guide 40 of the second wing 30 and is secured at the distal end 24.

With reference to FIGS. 1-5, operation of the device 10 will now be described. With the suture 48 in position as described above and as illustrated in FIG. 1A, the first button 16 can be depressed (FIG. 2) to move the first wing 28 and the second wing 30 into the extended position of FIG. 2A. The second button 18 can be depressed (FIG. 3) to move the first and the second needles 32 and 34 to the extended position in which the needles 32 and 34 extend through the openings 42 in the first and the second wings 28 and 30.

From the extended position of FIG. 3A, the first and the second needles 32 and 34 revert to the retracted position. As the first and the second needles 32 and 34 retract, the suture 48 is captured by the retention surfaces 44 and 46 and the first and the second wings 28 and 30 can be moved back to the retracted position by pressing the third button 20, as illustrated in FIGS. 4 and 4A. As the first and the second needles 32 and 34 retract, they pull the suture 48 such that the loop 54 extends out from within the distal end 24, as illustrated in FIG. 5.

With additional reference to FIGS. 6-12, use of the device 10 to repair a meniscus 80 having a tear 82 is illustrated. To close the tear 82, the suture 48 is attached to the distal end 24 of the device 10 and the distal end 24 is inserted through the meniscus 80 and through the tear 82. The tissue piercing pointed tip 26 facilitates insertion of the device 10 through the meniscus 80.

As illustrated in FIG. 7, after the distal end 24 of the device 10 is inserted through the tear 82 and the meniscus 80, the first button 16 is pressed to move the first and the second wings 28 and 30 to the extended position. With reference to FIG. 8, the first and the second needles 32 and 34 are moved to the extended position by pressing the second button 18. The device is positioned such that as the first and the second needles 32 and 34 move to the extended position they form two holes in the meniscus 80 through the tear 82, which is in addition to a hole created by the tip 26 of the device 10.

With reference to FIGS. 9 and 10, the first and the second needles 32 and 34 automatically return to the retracted position from the extended position and the first and the second wings 28 and 30 return to the retracted position by pressing the third button 20. As the first and the second needles 32 and 34 retract, they engage the suture 48 by way of the retention surfaces 44 and 46 and pull the suture 48 through the tear 82 by way of the holes created by the needles. Withdrawing the device 10 from within the tear 82 and the meniscus 80 further pulls the suture 48 through the tear 82 and causes the loop 54 of the suture to be withdrawn from within the distal end 24. With additional reference to FIGS. 11 and 12, tension is applied to the first end 50 and the second end 52 of the suture 48 to close the tear 82. The suture 48 can be tied into a knot to secure the suture 48 in place. The hole remaining in the meniscus 80 created by the tip 26 can be used for a variety of different purposes. For example, the hole can receive a meniscal conduit for directing a variety of different biologics, such as nutrients, to the meniscus 80.

With additional reference to FIGS. 13-15, another suture device according to the present teachings is illustrated at reference numeral 110. The device 110 includes a main body 112 and an extended or elongated shaft portion 114 that extends from the main body 112. The main body 112 includes at least one button, switch, or any other device suitable for operating the device 110. As illustrated, the device 110 includes a first button 116, a second button 118, and a third button 120. The device 110 can include any suitable number of buttons for operating the device 110.

The extended shaft portion 114 includes a proximal end 122 and a distal end 124. The proximal end 122 is mounted to the main body 112. The distal end 124 is opposite to the proximal end 122. The distal end 124 includes a pointed conical tip 126, a single suture support illustrated as a single retractable wing 128, and a single suture capturing device illustrated as a single needle 130. The pointed conical tip 126 is designed to pierce tissue. The pointed conical tip 126 includes or defines an opening 132. The opening 132 can be located at any suitable location on the tip 126.

The retractable wing 128 can include a suture guide and a needle opening. The suture guide can take the form of any suitable device for guiding a suture from the extended shaft portion 114 around the wing 128 and to the tip 126. For example, the suture guide can take the form of a recess, indentation, or c-channel formed in the wing 128, such as the recess 40 of FIG. 2A. The needle opening is an opening in the wing 128 that extends completely through the wing 128 and is sized to receive the needle 130.

The wing 128 is movable between a retracted position in which the wing 128 does not extend from the distal end 124 and an extended position (FIG. 13) in which the wing 128 does extend from the distal end 124. The wing 128 is movable to the extended position by actuating the first button 116. The wing 128 is movable to the retracted position by actuating the third button 120.

The needle 130 can be any device capable of penetrating biological matter, such as meniscal tissue. The needle 130 includes a retention surface. The retention surface can be any suitable surface or device for retaining and/or capturing a suture. For example, the retention surface can be a hook or notch formed within the needle 130, such as is illustrated at reference number 44 of FIG. 3A.

The needle 130 is positioned at a side portion of the distal end 124. The needle 130 is aligned with the wing 128. The needle 130 is movable between a retracted position (FIG. 13) and an extended shaft position (FIG. 14). In the retracted position, the needle 130 does not protrude from the extended shaft portion 114. In the extended position, the needle 130 protrudes from the extended shaft portion 114 and extends through the needle opening of the wing 128. The needle 130 can be moved from the retracted position to the extended position by pressing the second button 118. The needle 130 automatically returns to the retracted position after reaching the extended position.

The distal end 124 can receive any suitable fastening device for use in various surgical procedures, such as repairing a meniscal tear. The fastening device is illustrated as a suture 134. When in use, the suture 134 is mounted to the distal end 124 such that a first end 136 of the suture 134 is mounted to, or proximate to, the wing 128 and a second end 138 extends through the opening 132 of the tip 126 and is mounted within the distal end 124.

FIGS. 13-15 illustrate use of the device 110 to repair a meniscus 150 having a tear 152. To close the tear 152, the device 110 is inserted through the meniscus 150 and the tear 152, as illustrated in FIG. 13, such that the distal end 124, and the wing 128 in particular, pass entirely through the meniscus 150. The pointed tip 126 permits the device 110 to pierce the tough meniscus 150. The device 110 is inserted through the meniscus 150 with the wing 128 in the retracted position.

After the device 110 is inserted through the meniscus 150, the first button 116 is pressed to move the wing 128 to the extended position, as illustrated in FIG. 13. With the wing 128 in the extended position, the second button 118 is pressed to move the needle 130 to the extended position, as illustrated in FIG. 14. As the needle 130 moves to the extended position, the needle 130 extends through the tear 152 to create a hole in the tear 152. Thus, the device 110 creates only two holes through the tear 152, the first hole is created by the pointed tip 126 and the second hole is created by the needle 130.

After reaching the extended position, the needle 130 returns to the retracted position. As the needle 130 returns to the retracted position, the retention surface of the needle 130 captures the suture 134 and pulls the suture 134 back through the meniscus 150 and the tear 152. After the needle 130 captures the suture 134, the wing 128 is retracted by pressing the third button 120. As the device 110 is withdrawn back through the tear and out of the meniscus 150, the first end 136 of the suture is pulled through the hole formed by the needle 130 and the second end 138 of the suture 134 is pulled through the hole formed by the tip 126, as illustrated in FIG. 15. The suture 134 can then be tensioned and secured, such as by throwing a knot, to close the tear 152.

With additional reference to FIG. 16, the device 10 can also be used to close and repair a tear 154 in a rotator cuff 156. The device 10 can be used to repair most any type of rotator cuff tear, including a margin convergence tear and the tears described in United States Publication No. 2006/0029633 filed on Aug. 3, 2004 and assigned to Biomet Sports Medicine, LLC of Warsaw, Ind., which is incorporated herein by reference. To repair the torn rotator cuff 156 the device 10 is used in substantially the same way described above to repair the tear 82 of the meniscus 80 using the suture 48. Therefore, the above described method for repairing tear 82 can also be used to repair the tear 154 in the rotator cuff 156 using a suture 158. For example, the device 10 pierces the rotator cuff 156 with the tip 26 such that the device 10 is transverse to the tear 154 and extends through both a first side of the tear 154 a and a second side of the tear 154 b. Further, the device 110 can also be used to repair the rotator cuff 156.

With reference to FIG. 17, the device 10 can also be used to repair a rotator cuff 160 that has separated from a humerus bone 162. Most any type of rotator cuff separation can be repaired using the device 10, such as the separations described in U.S. Pat. No. 6,514,274 filed on Feb. 4, 2003 and assigned to Biomet Sports Medicine, LLC of Warsaw, Ind., which is incorporated herein by reference. As illustrated, the device 10 can be inserted through a bone hole 164 in the humerus 162 to pierce the rotator cuff 160 using the pointed tip 26 of the device 10. The bone hole 164 can be formed using any suitable device, including the device 10. The tip 26 is a bone piercing tip that can be driven through the humerus bone 162. After the device 10 has pierced the rotator cuff 160, it can be used to insert a suture 166 through the rotator cuff 160 in the same manner described above for inserting the suture 48 through the meniscus 80, as illustrated in FIG. 11. Therefore, the above method for threading the suture 48 through the meniscus 80 can also be used to thread suture 166 through rotator cuff 160. After the suture 166 is threaded through rotator cuff 160, the suture 166 can be secured to the humerus bone 162 using in any suitable manner, such as with a bone plate 168. One skilled in the art will appreciate that the device 10 can be inserted in the opposite direction whereby it pierces the rotator cuff 160 prior to extending through the humerus bone 162. Further, the device 110 can also be used to repair the rotator cuff 160.
